4.5.2 Motor-less operation in upper side
Connect the upper side to the driver before the motor-less operation.
(1) Motor-less operation
Without connecting the servo motor to the driver, output signals or status displays can be provided in
response to the upper side commands as if the servo motor is actually running. This operation may be
used to check the upper side sequence. Use this operation with the forced stop reset. Use this operation
with the driver connected to the upper side.
To stop the motor-less operation, set "Disabled (_ _ _ 0)" of "Motor-less operation selection" in [Pr.
PC05]. The motor-less operation will be disabled from the next power-on.
